Dems in Carson City

The Democratic candidates for President will all appear at a forum in Carson City, Nevada today -- all except Barack Obama, that is -- beginning at 3:00 eastern time. George Stephanopoulos moderates, and the candidates appear sequentially, not in debate format. AFSCME hosts, so the crowd will be jam-packed with union folks; the crowd responses might be the most interesting element of the event. You can watch on ABC News's subscriber-based online service, or free on C-SPAN (www.c-span.org).
